Parking Brake Spring Length?

Another screw up on my car. What is the nominal spring length for the Parking Brake (PM) cables in the L/R and R/R brake assemblies? I see a squashed spring in both brake assemblies when PB handle is not pulled. I recall the OEM spring lengths being 4-4 1/2 in when NOT activated nor not compressed. Too much spring compression initially will not allow brake shoes to expand and contact brake hub. .

Why does DORMAN and RIGHT STUFF have 5 1/2 in spring length?I called RIGHT STUFF and they assured me OEM specs were used and I screwed up. Time for a modification with a
grinder (carefully!!!!).

Brake issues all over and you guys solved or recommended solutions. Appreciate all the help.

Love MOPAR. Thx and hope to hear from the best.
